"Eldrid was the first person Eirik had known who made him feel so comfortable that he dared to keep quiet."

"This was no doubt why Olav, in his heart, had always held greater affection for Arnvid than for any other man. Arnvid was so brave that he never feared bending down, if need be, to let someone place their cross on his back."

So many examples of Eirik's inconstancy in chapter V!
